Femoral head prosthesis

摘要

The ceramic articular head (1) of a femoral head prosthesis is fixed on a metallic push-on part (3) in which a hollow cylindrical, stem-like extension (2) of the articular head (1) sits tightly on a cylindrical push-on part (3). The outer jacket of the extension (2) is conically widened toward the apex of the articular head (1) and inserted in a groove (7) which also widens conically toward the apex of the articular head (1). The groove (7) is formed by a collar (8) which surrounds the push-on part (3) annularly on the outside. In the novel conical push-on connection the articular head (1) is exposed only to pressure and no longer to traction. <IMAGE>
